Pikachu and Salandit were at the arcade together, the two having a gaming day out just because. There really wasn’t much reason behind it other than a phone call that resulted in,

“Wanna go to the arcade?? I wanna go to the arcade!”

“Uhhh… yeah, okay. I’m not doing anything to day.”

And that was about it. A sudden desire from Salandit and Pikachu being more than happy to indulge in that desire as well. Besides, arcades were fun! Tons of games classic and modern alike to enjoy. It was a pretty large arcade at that, split into two sections: Games Arcade and Prize Arcade. The games side held all of the iconic arcade classics while the prize side had a bunch of arcade style games that rewarded various amounts of tickets based on your performance with said tickets being converted to points at a ticket counter in order to buy various prizes.

Salandit had gone to the Prize Arcade while Pikachu stayed on the gaming side, enjoying a solo game of Sobble Bobble. “Pikachuuuuu~!” Pikachu’s ear twitched when he’d faintly heard a voice calling out to him among all the arcade noises and distant chatter of its patrons. Looking away from the screen, he saw a Pawmi running up to him at an almost alarming speed before they jumped at him, tackling the mouse onto the ground with impressive force. “Pikachu~!!”

“Gah! P-Pawmi, hi hello—oof! Oww, e-easy there!” Pikachu chuckled and laughed from the affectionate assault of being aggressively nuzzled into by the smaller rodent.

“Hiiii big brother~! I haven’t seen you in so long, I missed you I missed yooou~!” Pawmi squeaked, clinging onto the Alpha and squishing against him.

“Jeez, it has been… some time, huh?” Pikachu recounted, giving the happy little electric-type a pat on the head.

“Five years, you dork! Why don’t you ever call or visit??” Pawmi pouted and huffed, bumping against Pikachu’s chest. “Well… okay the visiting part is a bit of a tall order having to travel [I]continents[/I] and all. But why don’t you call??”

“I... just don’t have any of your phone numbers.” Pikachu scratched the back of his head with a sheepish little chuckle. “But you’re here now...wait. [I]You’re here now.[/I] What—how—why? When?? What [I]are[/I] you doing here anyway, Pawmi?”

“I moved! For college~ I’m attending Albacore University here on campus! But I didn’t think I’d see you here, big bro~” Pawmi giggled, tail wagging excitedly and giving Pikachu a lick on the cheek.

“Well… wow, that’s great for you! And what a coincidence too, you being here and all. I actually [I]live[/I] here in case you were wondering what I’m doing here.” Pikachu was surprised to know that he had family living in the same town as him now. Of all the places Pawmi could have enrolled in, what are the chances of ending up here?

“Ooo you live here?! So like.. we’d be able to see each other and hang out and stuff again??” Pawmi’s eyes lit up with child-like wonder, Pikachu nodding and patting them on the head again.

“Well, yeah in fact~ We’ve got lots of catching up to do now!” Pawmi squealed and jumped happily, nuzzling Pikachu’s cheek and letting their pouches spark affectionately before getting off of the taller male and letting him stand up. “Man, five years go by quick, huh? Feels like it was only months ago I last saw you, mom, and dad. You were just an excitable high school freshman when I last saw you. Now you’re…” With Pawmi now standing in front of him, it gave Pikachu a chance to really look them over. Pawmi was a semi-anthro girl, able to stand on two feet unlike her feral counterparts though not quite as humanoid figured as most fully anthro Pokemon. A short stack that appeared to be about a foot shorter than Pikachu, she really had a growth spurt from the 14-year old she was 5 years ago. Now 19 and attending college, her previously flat chest had developed beautifully into quite the bouncy and soft looking rack with quite a bit of cleavage and even a bit of her bra visible under her loose fitting daffodil yellow blouse top. She had a small bit of pudge on her but that just made her even more sexy looking, a belly that looked soft for kisses and rubbing and hips that Pikachu had a sudden urge to grab and hold… Her thighs were nice and shapely as well, rather thick but looked quite toned in her black track shorts. She must do a lot of leg based athletics, he figured.

Pikachu suddenly remembered who he was staring down and shook his head. That was his little sister he was eyeballing with those thoughts, what was he doing!? Simple. Being attracted to his little sister, that’s what. Family was not safe from Pikachu’s libido.

“You’ve really… [I]grown[/I], that’s for sure.” Pawmi giggled and placed a paw on her hip.

“Grown? I sure have, big bro~” She giggled again, grabbing her chest and groping herself a bit before hefting out her large breasts towards Pikachu as if tempting him. Fuck… was she trying to tell him something? “I can say the same about you~ You always were a big strong chu, being an Alpha and all. But wowie, you’re so big and cute!” She cooed, her tail wagging and nuzzling up against Pikachu again. “Hehehe… you’ve [I]really[/I] grown that’s for sure~” She purred into his ear, her voice taking a rather sultry tone there. Pikachu tensed up a bit and went a little red. Was she flirting with him? His own sister? Trying to get laid with him or something? Granted, last time they saw each other before he moved out, he’d just turned 18, being 4 years older than her. Thoughts like these never crossed either of their minds, at least not with each other. Sure, Pikachu had sexual thoughts in high school like most teenagers with their crazed hormones would, but he hadn’t exactly been on the prowl for his little sister then, being more interested in being a good, loving big brother than trying to fuck a 14-year old girl when he was 17.

But now here she is, fully grown adult, 19-years and attractive head to toe and he was beginning to have a hunch that Pawmi may have had some repressed thoughts or desires for her older brother that she could finally indulge in now that she’s not only an adult but also reunited with him. “Heeey Pikachu~” She rubbed Pikachu’s back with her tail and nuzzled him with a purr. “You know, I think you’re a lot happier to see me than I thought~” She pointed downward with a smirk and Pikachu’s blush darkened. He didn’t need to look, he knew just what she meant. He was pitching a tent in front of his sister… because of his sister. She giggled at his expense and then grabbed it, causing Pikachu to tense up with a sharp gasp. “Gosh… what did you think I meant when I said you’ve grown too~?” She purred into his ear, teasing the electric mouse with gentle squeezes at his large cock. “Golly, you’re so [B]hung…[/B] how the heck do you put this in girls??”

“A-ahh.. P-Pawmi, what… w-we’re in public…” Pikachu bit his lip. Despite them being in a public place, the arcade was dimly lit and [I]very[/I] occupied with all sorts of games and machines all over the place that essentially made their standing out in the open as secluded as being in a bedroom. At least as long as they were subtle enough.

“Public~? I thought you’d ask why I was doing this, but…” Pawmi purred, letting go of Pikachu’s tent and slipping her paw into his pants instead to grip his length directly. Pikachu moaned softly, the heat of his dick radiating onto her paw as she started pumping him gently. “I guess I wasn’t the only one who wanted to do this..~”

“N..nnnhh n-no I never thought of you like that… I-I just wanted to be a good big brother a-and make sure you had someone to play with a-and talk to in the family around your age… o-ooh fuck…” Pikachu groaned and quivered. Sure, he never thought of her like that then, but as soon as he got a look of her now, the thoughts were immediately there and he was not at all objecting to this. The only problem was… well it needn’t be repeated.

“Wowie zowie, Pika… I can’t even wrap my whole paw around it, you’re so [B]thick~[/B]” Pawmi moaned into his ear, jerking Pikachu off while grabbing one of his paws with her own and bringing it to her breast. “C’mon… don’t you miss me? Go ahead… get a [B]feel[/B] for your little sis again~” Pikachu, flushed as could be, didn’t hesitate when she put his paw on her breast. He groped and kneaded into the large, soft breast, getting more moans out of his horny sister. Fuck, her body felt so soft… but he needed to stop this before it escalated to the point of no return. His arousal was spiking by the stroke and if she kept egging him on like this, he’d end up with her bent over one of these machines and taking a whole shower in the amount of cum his enlarged balls would produce.

Another target for his Deep Dicking December, he figured.

“Ah… P-Pawmi wait… I c-can’t right now…” Pikachu groaned and, while he kept fondling her tits, he reluctantly pulled her paw away from his cock. “I’m… h-have you heard of No Nut November..?”

“Ooooo—oh! Oh golly wowzers, you’re not… are you actually~?” Pawmi’s eyes lit up again and she smirked deviously. Oh Arceus, what was she planning?

“Y-yeah and I’m getting close, the month will be over soon enough and… and if you be a good little sister and let me make it to the end, I’ll give you the most mind blowing, pussy pounding, titfucking, ass bouncing wild sex you could ever ask for from your own big brother~” Pikachu had to tempt her not to torment him or try to make him fail the challenge. He knew his sister could be a bit mischievous as her method of being a rebel or breaking rules and knowing that he was abstaining from sex for the month would likely make her even [B]more[/B] willing to have sex with him. Which was really fucking hot to Pikachu but also would be a huge problem.

“Hmmmmm… okay! I’ll let you finish your challenge. Buuuut… you gotta promise me we’ll have that super amazing sex together~”

“Y-yeah, we ca—”

“And! You gotta promise that we’ll have sex… without using a condom~”

“Wh-what?! B-but you could—”

“Promise it! We have amazing sex unprotected! [B]AND[/B] you cum inside my pussy~”

“Y-you could get pregnant, Pawmi!”

“Is that problem, big brother~?” No! It wasn’t a problem in the slightest, it was [B]really fucking hot[/B] to Pikachu that his own sister was [I]this[/I] horny for him. But for fuck’s sake, having a kid with his own sister was also really weird?? Sure, incest among Pokemon was extremely common and not frowned upon in the slightest—Pokemon weren’t like humans where incestuous conceiving very often resulted in very problematic issues for their children. In fact, inbreeding among Pokemon was actually more beneficial to their offspring more often than not because of passing down their healthiness and IVs through the generations.

But that was the one part of incest that really weirded Pikachu out on a personal level. He loved Pawmi deeply and dearly as a sibling and would do anything for her. Almost. Impregnation among family felt so… off to him. It wasn’t something he necessarily saw as some ultimate symbol of romance of anything—Arceus knows how many babies he might have out there with all the prostitutes that begged him for unprotected creampies—but something about getting intimately involved in a kid’s life and actually being a present parental figure...doing that with a family member made it feel like he’d be romantically involved with his sister. Pikachu would happily have sex with family but he could never see himself romantically involved with them.

“Oh! I almost forgot one more condition~”

“Wh-what—something [I]more?[/I]” Pikachu was really getting wrung out by this excitable girl. She was really gonna milk this opportunity out just so he wouldn’t have to deal with her trying to milk his balls for the rest of the month, huh?

“Mhmm! Ooooone more thing. I promise, you’ll like this condition~!” Pawmi giggled then pulled Pikachu over to the Sobble Bobble machine. From the side of the machine, the two of them would be in the corner, far away from the main area of the arcade, a spot where she was certain no one would bother walking by and seeing them unless someone wanted to play on the machine. Gazing into his eyes, she’d turn away from him and bend over, pressing her front against the wall and reaching down to peel her tight fitting shorts down, exposing her plump, soft ass and juicy cunt, strings of nectar attaching to her panties. “Eat my pussy, big brother~ I’m horny as heck and seeing you just made it worse~ Make me cum and I won’t bother you for sex for the reeeest of the month~” Fuck… she was a sexy ass freak. Pawmi was right though, Pikachu [I]did[/I] like this condition. So much so that he needn’t be told twice, already on his knees with paws on her fat ass, kneading into the pliable, soft flesh and spreading her bountiful booty to bury his tongue right into that sopping tunnel.

“O-ohh! I’ll t-take that as a yeesssaaah~” Pawmi moaned out, not afraid to express herself as all the loud arcade noises easily drowned out any noise they made. Pikachu went straight to work, letting out his hunger for the sexy Pawmi. Flicks of his tongue ground against clenching walls, her flavor slightly bitter with a strong sweet aftertaste that he loved. His lips crashed against hers and he began fully french kissing Pawmi’s cunt, sucking her plump pussy lips and really digging his tongue deep, wriggling and exploring her canal, thrusting and swirling about while fondling her big bubble butt. All the while, Pawmi shook and moaned out, pushing her ass against her brother’s face and trembling above the hungry and horny male. Pikachu could feel the wild throbs in his pants; he wanted to stand up and fuck Pawmi’s brains out more than anything right now, but he had to resist. Arceus give him strength to endure this beautiful ass female without losing the challenge.

“Oohh ffffuudge, b-big brother~ Mnnh b-big bro! There there there, l-lick it lick that spot~!” Pawmi cried when Pikachu struck her g-spot, that pleasure button being violently stimulated right away with rapid flicks and licks, occasionally digging his tongue into Pawmi’s sweet spot and listening to her squealing cries and feeling her smother him against her big ass. He persisted in making out with her vagina, lips sucking and tugging Pawmi’s own, keeping her writhing and trembling all over, uncontrolled sparks crackling in her cheek pouches and her tail starting to twitch and flick frantically. Yeah, those were telltale signs alright, the signature signs of a Pikachu-like species on the edge of an orgasm. Pikachu decided to really make it worth her while, knowing his little sister would likely be fantasizing and lusting over his cock for the rest of the month, struggling just as much as he would be with knowing she won’t get her pussy stuffed and fucked up on his dick until December. So he’d make sure her first orgasm at the paws—tongue rather—of her brother would be well worth the next week and a half of waiting for more.

His own cheek pouches surged and a course of sparks ran from his pouch into his mouth and out through the tongue, charging the girl’s depths with an intense pleasure shock that got a scream out of Pawmi that, were anyone close enough, would definitely have been heard over the arcade ambiance, even if only barely. “MMHAAAAH! P-PIKAAAA~!” She cried aloud for her big brother, Pikachu tugging out of her vagina to get splashed in one hell of an orgasm. Fuck… she’s a screamer [B]and [/B]a squirter… Arceus in heaven help this poor mouse not stand up and fuck the hell out of this queen right here and now. He [B]loved[/B] screamers and squirters,  their orgasms were always so damn intense, watching Pawmi’s trembling legs to her wagging tail, the bolts of electricity crackling more violently in her cheek pouches, and her nonstop cries, the shaky, voice cracking moans of her cumming so hard. Pikachu latched back on to drink, that bittersweet essence driving him wild. Fuck! This would be an easy favorite drink if he could get this regularly.

He probably could… Pawmi was the one that initiated the idea of them having sex after all. She was very much into the thought of them fucking. Though… he had to wonder how frequently she’d be willing to do it. Questions for December.

“Aah… hah, h-holy… holy moly g-grandoly, big brother…” Pawmi huffed and panted, trying to recollect herself and keep standing on wobbling legs. Pikachu kissed her cunt and pulled her shorts and panties back up with a pat on her ass as if nothing ever happened. He grabbed her gently, helping her keep up on those jelly legs as he turned her around to face him and gave her a quick kiss on the lips.

“December…” He growled at her, gazing into Pawmi’s eyes hungrily. “...I’m going to [B]fucking [I]ruin you..~[/I][/B]”
